Microscopic image capture apparatus and microscopic image capturing method
View Patent ↗A microscopic image capturing apparatus and method are provided. First, the entire area of a slide glass on a stage is divided into field size sections (low-magnification sections) of a low-powered objective lens. The stage is transferred perpendicular to an optical axis, and image information is sequentially obtained for each low-magnification section. Each low-magnification section is divided into high-magnification size sections (high-magnification sections), and a high-magnification image is captured using a high-powered objective lens only in high-magnification sections corresponding to a sample. A high-magnification image is generated by correctly maintaining the relative position between the obtained image information and an area corresponding to high-magnification sections which are not captured, and high-magnification composite image information of the sample is generated.

a macro capture device for collectively capturing an entire area of a slide glass;
a macro image information dividing device for dividing image information on the slide glass obtained by the macro capture device into high-magnification size sections corresponding to a magnification of a predetermined high-powered objective lens;
a sample image discrimination device for checking each of the high-magnification size sections to determine whether there is sample image information of the sample in the obtained image information for each of the high-magnification size sections, and for discriminating (i) each high-magnification size section including the sample image information as a sample image inclusion section and (ii) each high-magnification size section including no sample image information as a sample image exclusion section;
a high-magnification image capture device for capturing high-magnification image information using the predetermined high-powered objective lens only for each said high-magnification size section discriminated as the sample image inclusion section; and
an image information generation device generating high-magnification composite image information about the sample on the slide glass by generating a high-magnification image such that a relative position between (i) an area of the high-magnification image corresponding to the high-magnification image information obtained by the high-magnification image capture device and (ii) an area of the high-magnification image corresponding to each said high-magnification size section discriminated as the sample image exclusion section and not captured by the high-magnification image capture device, can be correctly maintained.
2. The apparatus according to claim 1 , wherein the image information generation device comprises a dummy data assignment device for assigning dummy data predetermined to be similar to a background of the sample image as image information for each said high-magnification size section in the area of the high-magnification image not captured by the high-magnification image capture device.
3. The apparatus according to claim 1 , further comprising an arbitrary image information generation device for generating arbitrary image information having at least one of a different magnification, a different position, and a different area, based on the high-magnification composite image information generated by the image information generation device.
4. A microscopic image capturing method for capturing a sample image of a sample, said method comprising:
collectively macro-capturing an entire area of a glass slide;
dividing image information on the glass slide obtained by the macro-capturing operation into high-magnification size sections corresponding to a magnification of a predetermined high-powered objective lens;
checking each of the high-magnification size sections to determine whether there is sample image information of the sample in the obtained image information for each of the high-magnification size sections, and for discriminating (i) each high-magnification size section including the sample image information as a sample image inclusion section and (ii) each high-magnification size section including no sample image information as a sample image exclusion section;
capturing high-magnification image information using the predetermined high-powered objective lens only for each said high-magnification size section discriminated as the sample inclusion section; and
generating high-magnification composite image information about the sample on the slide glass by generating a high-magnification image such that a relative position between (i) an area of the high-magnification image corresponding to the high-magnification image information obtained by the high-magnification image information capturing operation and (ii) an area of the high-magnification image corresponding to each said high-magnification size section discriminated as the sample image exclusion section and not captured by the high-magnification image information capturing operation, can be correctly maintained.
5. The method according to claim 4 , wherein the generating operation comprises assigning dummy data predetermined to be similar to a background of a sample image as image information for each said high-magnification size section in the area of the high-magnification image not captured by the high-magnification image information capturing operation.
6. The method according to claim 4 , wherein arbitrary image information having at least one of a different magnification, a different position, and a different area is generated based on the generated high-magnification composite image information.
